have attained a pressure of at least 200 kPa(2.0 bar/29 psi).
If a pressure of 200 kPa (2.0 bar/29 psi) hasbeen attained after five minutes, see "Tire pres-sure reached" (Ypage 318).
If a tire pressure of 200 kPa (2.0 bar/29 psi) hasnot been attained after five minutes, see "Tirepressure not reached" (Ypage 318).
If tire sealant has escaped, clean it off affectedareas as quickly as possible. It is preferable touse clean water.
If your clothes are soiled with tire sealant, havethem cleaned with perchloroethylene at a drycleaner as soon as possible.
Tire pressure not reached
If a tire pressure of 200 kPa (2.0 bar/29 psi) hasnot been attained after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of thefaulty tire.Tire sealant may escape when the filler hose isunscrewed.
XVery slowly drive forwards or reverse approx-imately 30 ft (10 m).
XPump up the tire again.
After a maximum of ten minutes, the tire pres-sure must be at least 200 kPa (2.0 bar/29 psi).
GWARNING
If the required tire pressure is not reached
after the specified time, the tire is too badly
damaged. The tire sealant cannot repair the
tire in this instance. Damaged tires and a tire
pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
Tire pressure reached
GWARNING
A tire temporarily sealed with tire sealant
impairs the driving characteristics and is not
suitable for higher speeds. There is a risk of
accident.
You should therefore adapt your driving style
accordingly and drive carefully. Do not exceed
the specified maximum speed with a tire that
has been repaired using tire sealant.
The maximum permissible speed for a tiresealed with tire sealant is 50 mph (80 km/h).The upper part of the TIREFIT sticker must beaffixed to the instrument cluster in the driver'sfield of vision.
If a tire pressure of 200 kPa (2.0 bar/29 psi) hasbeen attained after ten minutes:
XSwitch off the tire inflation compressor.
XUnscrew the filler hose from the valve of thefaulty tire.Tire sealant may escape when the filler hose isunscrewed.
XStow the tire sealant bottle and the tire infla-tion compressor.
XPull away immediately.
XStop after driving for approximately tenminutes and check the tire pressure with thetire inflation compressor.The tire pressure must now be at least130 kPa (1.3 bar/19 psi).
GWARNING
If the required tire pressure is not reached
after driving for a short period, the tire is too
badly damaged. The tire sealant cannot repair
the tire in this instance. Damaged tires and a
tire pressure that is too low can significantly
impair the vehicle's braking and driving char-
acteristics. There is a risk of accident.
Do not continue driving. Contact a qualified
specialist workshop.
In cases such as the one mentioned above, con-tact an authorized Mercedes-Benz Center. Orcall 1-800-FOR-MERCedes (in the USA) or1-800-387-0100 (in Canada).
XCorrect the tire pressure if it is still at least130 kPa (1.3 bar/19 psi). See the Tire andLoading Information placard on the B-pillar onthe driver's side or the tire pressure table inthe fuel filler flap for values.
XTo increase the tire pressure:switch on thetire inflation compressor.

Fuses
Important safety notes
GWARNING
If you manipulate or bridge a faulty fuse or if
you replace it with a fuse with a higher amper-
age, the electric cables could be overloaded.
This could result in a fire. There is a risk of an
accident and injury.
Always replace faulty fuses with the specified
new fuses having the correct amperage.
Blown fuses must be replaced with fuses of thesame rating, which you can recognize by thecolor and value. The fuse ratings are listed in thefuse allocation chart.
The fuse allocation chart is on the fuse box in thecargo compartment (Ypage 328).
If a newly inserted fuse also blows, have thecause traced and rectified at a qualified special-ist workshop, e.g. an authorized Mercedes-BenzCenter.
